Patented Apr. 12, 1921.

Application filed May v12, 1919. Serial No. 296,386.

To all whom it may concern.'

Be it known that I, ARTHUR G. STEVEN- soN, of Rochester, in the county of Monroe and State of New Yor have invented cer-` tain new and useful Improvements in Brushes; and I do hereby declare the following to be of the same, reference being had to the accompanyin drawings, forming a art of this speci cation, and to the re erencenumerals marked thereon.

This invention relates to brushes of the variety provided with a container or reser- Voir, for detergent or other material to be used with the brush, and more particularly, to brushes of the variety in which the ma-l terial is carried in a handle which is detachable so that. it may be applied directly to the surface of the brush and the container may be closed when not in use, one object of the invention being to provide a brush .of this description which is simple and eiiicient in construction and cleanly and convenient in operation.

A further object is the provision of a brush of the above character so constructed that the reservoir is necessarily closed after an application of the material to the brush, thus insuring a cleanly and sanitary condition of the parts and obviating the hardening of the material and clogging of the reservoir which results from leaving the latter open and exposed to the air.

4Another object is the provision of simple and convenient means` for refilling the reservoir from a supply container such as the usual collapsible tube. A. still further object is to provide a simple and durable constructionof the operating parts whichare inexpensive to manufacture and not likely to get out of order. To these and other ends the invention resides in certain improvements and combinations of parts,all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

ln the drawings:

Figure 1 is a side elevation of a brush, partly broken away, having the invention applied thereto.

Fig. 2 is a top plan View of the same with the handle portion in central section.

Fig. 3 is a fragmentary view of the brush head partly in section. j

a full, clear, and exact description .the invention. The present Fig. 4 is a fragmentary view showing the handle in central section with a refilling container attached thereto.

ig. 5 is a transverse section on the line 5-5a of Fig. 2.

Fig. 6 is a similar view on the line 61--6a of Fig. 4.

Fig. 7 is a View tached for applying the material to the bristles. The invention, in the embodiment at present preferred as best illustrating the principles involved, is disclosed as applied to a tooth brush, but is, of course, vcapable of a wide variety of applications, and also of various modifications of the details of construction and 'operation within the scope of embodiment comprises a brush head 10 provided with the usual bristles 11 and having a portion 12 to whichl is attached a handle 13, the latter being detachably secured to the portion 12 of the brush head preferably by means of a reduced portion 14 on the-handle which is received 1n a recess or socket 1'5 formed in the portion 12, the parts being provided with interengaging screw threads 16 so that the head and handle may be securely fastened together for a brushing operation or readily detached for applying material to the brush as hereafter described.

rlhe handle 13 is hollow, having a substantially cylindrical bore 17 forming a reservoir for paste, powder or other material to be used with the brush, the reservoir being closed at its inner end tition 18 which supports the reduced portion 14, and open at its opposite or outer end where it is formed interiorly with screw threads 19 with which engages a reduced threaded end of a closure plug 20. The latter has formed therein, centrally of its interior surface, a bearing 21, and the portion 14 at the other end of the handle has formed therein a Second bearing 22, in which bearings is rotatably supported a rod 23 which is threaded at its portion within the reservoir, and projects outside the portion 14e of the handle where it terminates in a nozzle 2li having an opening or channel 25 extending centrally thereof and communicating through side openings 26 with the inner end of the reservoir. The rod carries adjacent the wall 18 a lug or fiange 27, and adjacent preferably by a par-V showing the handle de other for a brushing the end of the portion 14 the rod has fixed thereto a knurled fingerpiece 28 by means of which it may be conveniently rotated in its bearings.

Within the reservoir is a plunger or piston 29 having threaded engagement with the rod 23 and provided with a packing 30 which snugly engages the sides of the reservoir and prevents the rotation of. the plunger during the rotation of the rod. 1t is ap parent that after the reservoir has been filled With material, rotation of rod 23 b means of the fingerpiece 28 serves to a vance the plunger and force the material from the nozzle 24 to apply it to the bristles of the brush as illustrated in Fig. 7 A disk 31 is provided at the inner end of recess 15, forming a closure for nozzle 24 when the brush head and handle are attached to each operation.

As illustrated in Fig. 4 the plug 20 at the outer end of the handle may be removed and the threaded end 32 of the nozzle of a supply container, such as the ordinary collapsible tube, 33, may be inserted instead, the plug 20 being of a suitable size for this purpose so that the supply nozzle is brought in communication with the reservoir, at which time the rod is operated to bring plunger 29 to the outer position shown, Where ahy-pass 34, extending around the plunger, permits the material to be forced from the supply container to the reservoir to fill the latter, after which plug 2O may be reinserted and the brush will be ready for use.

In the operation desired to apply material from the reservoir to the brush, the handle is detached from the brush head and fingerpiece 28 is operated to advance the plunger an-d force a quantity of material from the nozzle 24 for application .to the ends of the bristles Where it is most effective. The handle is then attached to the brush head as shown in Fig. 2 in which position the brush is ready for use and the nozzle of the reservoir is closed bythe disk 31. The material is thus supplied to the brush in the most effective manner and the construction is suchthat the reservoir must be reattached to the brush before the latter can be used, thereby insuring the closure lof the reservoir. The invention thus overcomes the objectionable feature of a common form of reservoir brush in which the material is applied through the brush head at the base of the bristles Where it tends to harden and cake by exposure to the air and to close the outlet of the reservoir, the present invention thus having the advantages of being more cleanly and sanitary, and of applying the material to the ends of the bristles Where needed, instead of at their roots. The constructionis simple and inexpensive to manufacture and durable and convenient in opof the device, when it is eration, and lends itself readily to combination with a design of the article of neat and pleasing appearance.
